Daylight saving notes
In southern Australia, daylight saving time runs from the first Sunday in October to the first Sunday in April. That affects Australian Eastern Standard Time (AEST).

What is the time difference between KST and AEST?

Right now the time in Australian Eastern Standard Time (AEST) is Tuesday, June 30, 2026 · 3:54:05 AM. It ticks every second, so you’re always looking at the live AEST clock.
What time is it in KST right now?
And in Korea Standard Time (KST), it’s currently Tuesday, June 30, 2026 · 2:54:05 AM. Compare the two and the 1 hour gap is easy to see.
When is a good time to schedule a KST to AEST meeting?
For example, a 9:00 AM KST meeting takes place at 10:00 AM AEST. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.
How does daylight saving affect KST to AEST?
The labels KST and AEST are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
Why can you trust this KST to AEST converter?
Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so KST to AEST stays accurate for today and for any past or future date you type in.

Frequently asked questions
How many hours ahead of KST is AEST?

What time is it in AEST when it's 12:00 PM KST?

Do KST or AEST use daylight saving time?
Korea Standard Time (KST) is a fixed offset with no daylight saving; Australian Eastern Standard Time (AEST) observes daylight saving, alternating with AEDT.
Why might the real-world KST–AEST difference change during the year?
The labels KST and AEST are fixed offsets, so this converter is always exact. But Australian Eastern Standard Time's region switches between standard and summer time, so for part of the year you may actually want KST to AEDT. Always check which label a region is currently using before you schedule.
